Professional advice hacks on a painted home. We offer
helpful tips on what to do, and buy. The exterior paint on your home is the
first line of defense to help protect your homes structure. It is just as
important to keep it maintained as well.
The light colored residue on painted exterior surfaces is chalking
paint. So what causes chalking paint? The main cause of chalking paint is
exposure to sunlight. The ultra violet light breaks the binders in the paint
and releases the pigments. Another cause is the reaction between the binders
and oxygen which is called paint oxidation. Both processes have the same effect
on all finish types. Another cause is the paint quality; some paints tend to chalk
sooner than others such as Alkyd paints (oil based paint) this type of paint oxidizes
faster. So you may be thinking of quality of paint what type of paint should
you get for your home? There are many options such as latex, acrylic,
latex/acrylic blend and so on. As a good rule of thumb is "the more
expensive the paint the better and more the resins it has" The resins are
the binders that holds the pigment. The best option on the market today for
exterior paint is 100% acrylic. Cheaper paints tend to degrade faster such as
latex and acrylic/latex.
The proper cleaning of the chalky surfaces on a painted home
is to remove the residue using a pressure washer along using a mild, environmentally
friendly, soap. Allow the soap to sit and activate on the surface for 10-15
minutes and rinse the soap completely off using pressure cleaning techniques of
1500-2000 psi pressure on the machine. If you plan on repainting the home, it
is best to use an acrylic primer with mildewcide before paint finish coat is
applied.
Mold and mildew attacks the painted surfaces. Zinc oxide and
Titanium dioxide are common pigments in top coats that inhibit the growth of
mildew. Paints that contain linseed oil will develop severe mildew in warm,
damp climates such as Florida . It
is just as important to make sure your home is free of mold and mildew and kill
it off before painting. Since if the mold or mildew will grow thru new paint. A
mild household detergent without ammonia with sodium hypochlorite (fresh-new
household bleach) and warm water is a good cleaner for killing mold and mildew.
Take the necessary precautions and protect yourself, grass, and shrubbery. Wear
protected clothing, eye wear, and skin protecting gloves while using the
product cleaning method. Use a bristle brush while cleaning the effected areas
of mold and mildew. Make sure you rinse off the solution well before painting.
